Rare-earth-doped sesquioxide laser ceramics, such as Nd:Y2O3, Yb:Lu2O3, Ho:Y2O3, have been successfully fabricated using nano-crystalline powders synthesized with a spray coprecipitation method and a low-temperature vacuum sintering plus hot isostatic pressing (HIP) technique. High power high efficiency laser oscillations of the ceramics are experimentally demonstrated.
